Advanced Lighting Techniques in Cinema 4D

Lighting has a very important role to play in all things but especially in 3D as it is a lot harder to effectively use lighting in a realistic way using the standard light settings. Therefore it has become important for me to progress as an animator to incorporate more professional use of lighting by using the inbuilt lights in C4D.

This tutorial has been very useful in pointing out the fact that all 3D light is flat and does not react in the same way naturally occurring light does. Instead of bouncing off surfaces and bending the 3D light carries in one continuous line. Therefore some extra measures have to be taken to create a visually rich and high contrast images.

The introduction to 3 point lighting is also a game changer and although i already had some knowledge of this lighting technique i failed to use it before in  a 3D environment. Another point well made was using more than 3 points as the lights in 3D only pick up shadow, mid tones, and highlights whereas in reality there is five main points of light shadows, quarter tones, mid tones, three quarter tones and highlights. Therfore we must add in more soft lights to create a higher dynamic range of light. This effect can be achieved by adding in different layers of light slightly off point from each other and emitting slightly softer light each time.

I could just use GI (Global Illumination) with a HDRI image however this would defeat the point of the experiments and learning about lighting is the real goal here. It is also mentioned that GI is actually a pretty lazy way of lighting and can make you’re image look flatter, however using it alongside a proper lighting rig can improve the image/animation. Therefore I still need to learn proper lighting techniques to boost the potential of my overall animations.

Adjust the default light C4D – This is a quick way to change the position of the lights within a space. This could come in very handy and i feel it will definitely speed up my process as well.

Free Light Dome – A quicker alternative to GI as these are all separate lights it will be faster and also there is a lot more control over colour schemes and shadow maps.

10 Tips for better lighting in Cinema 4D – Similar stuff to the first video, however it does mention the use of different shadow types and features. It states that “Area shadows are by far the most superior shadow type as they offer high accuracy and the most control.”. However  “area shadows are the slowest to render. To speed things up you can decrease the number of samples and accuracy, this will give you results faster but also will introduce noise.”

So a lot to think about and experiment with…

PROJECT 5 – The Final Brief

For project 5 I will be revisiting C-TEX and making a further 2 videos to complete the C-TEX Colour package. These will be available after the client has made the initial purchase of the machine and therefore will go into a lot more detail about pre installation of the machine and also training there workers to use the machine, and also showing the managers how to get the right information that they need from the spreadsheet that the program creates. Detailing different information about the materials being tested.

The first video is the sales video which was completed for Project 3.

The second video is a pre installation guide –

Pre-Install Video Script

Should be less than 5 minutes

Thanks for buying c-tex colour, this video guides you through 2 things:

1. The information we need from you in order to manufacture c-tex colour ready for you

2. For you to prepare ready for the installation

So…the information we need.

Firstly, we need a photo of where you would like c-tex colour to be installed. Here are some examples…

Then we need some dimensions so we can fit c-tex colour to your machine

Here we show you the dimensions we need

Secondly we need to know the direction the fabric is flowing in: please indicate this with an arrow

Thirdly we need to know at which side of the machine you wish the PC and Operator monitor to be located

Also please take a photo of your length measuring wheel (if you already have this installed) so we can assess how to fit our encoder onto this

Lastly, machine construction: Please indicate the materials your machine is made of and thicknesses. For example, Solid Mild Steel 6mm thick, Mild Steel Box Section 2mm thick with section of 100 or Wooden Section 15mm.

Therefore, the photo you send us will need the additional information as shown here (photo with all details on)

We can then build c-tex colour to fit your machine

Onto the second step:

For the installation we need:

Network Access to machine area for us to connect the c-tex colour PC to your network

Electrical power: single phase

If you have not purchased a control cabinet from us and you will be providing yourselves this needs to be onsite when we arrive. We require minimum internal dimensions of Height: 1000mm, Width 600mm, Depth 600mm. The operator monitor can be mounted above the control cabinet of you can purchase a control unit with monitor surround.

If you have not purchased a PC from us and you will be providing yourselves, please ensure this meets the specification we list in our agreement document and is available when we arrive onsite

If you are running c-tex colour for an inline process, for example a continuous dye range or sanforiser or compactor we will also need a mains compressed air supply provided, to include a regulator and moisture capture mechanism.

When we arrive onsite for the installation we need to meet with your factory engineering manager and IT manager to present what we are going to be doing while onsite and what support we need.

We will also need a meeting room with a projector or large monitor in order to give a training presentation for 1 hour. For the training we will need your colleagues who will be: operating c-tex colour, analysing the results of c-tex colour and managing the implementation of c-tex colour.

Adam has done these rough storyboards which really helped me to visualise what exactly needed to be done in terms of 3D animations. As this is the job role i will be fulfilling for this final project. I will of course have to make some more detailed sketches of what exactly needs to be shown in 3D and camera movements etc, however this quick visual is very handy for mapping out the whole video 2 sequence.

 

The third video is a training video – Full Script to follow…

 

Cubic Texture Testing

For creating a texture for the fabric i thought it would be nice to add some motion. and creating a sense of enlarging the fabric to a macro level. For this i used cinema 4D and then rendered using different CEL renders to add growth to the piece.

 

I found this video and thought i could try and replicate it in a way. To show fabric texture but also to be visually interesting to draw in attention. This is conceptually sound and i think using some of my previsou design ideas could come in handy. By using not hypernurbs but filleting to curve off the edges making a smoother looking cube.

capturecapture-pn1g80636-texturefabric3

This is the piece i have rendered recently, unfortunately the quality is really poor just to speed up the process but the final piece will be better quality.

 

This is really to show the problem for the sales video, although after watching this i realise the drop in quality was because i put it through premier and then through after effects as i had some issues with transitioning so, it has been quite heavily edited. Also after some much needed feedback i have realised that there are still little spots of white in the wavy part and this is a bit confusing also the waves are a bit random and if they could be more uniform it would look a lot smoother and aid the friendly concept.

Another idea would be to add this texture footage to the first draft edit. the shirt showing the moving texture when zoomed in could look very flash and attractive to the eye. I also need to think about the computer program aspect of the video and show a computer running the c-Tex software.

I am quite pushed for time and Raed has said he will make one also so for now i think i will download a pre-made model off the internet and use this as a placeholder just to get the storyboard in motion. A nice looking one i found online – Computer Model

I also need to look at modelling the colour scanners for the installation video. This could be quite simplistic as if i make a simple and basic looking machine and then highlight the sensors on the machine in detail then it could have quite an interesting effect and really helps draw your eyes to the important parts of the machine hardware.

Something like this for example where the key ares are highlighted. could also use the C-Tex RGB colour scheme to highlight these parts.

I have also found a very effective After effects video which eradicates the transitioning problem i had with the previous cube texture testing. Therefore this should hopefully eradicate the poor quality and compression. This has been done by using some very technical expressions but should help to speed up the whole process. So i am looking forward to trying this out for myself.

More to come soon….
